Dr. Gabrielle Lyon is a functional medicine physician specializing in the concept of muscle-centric medicine, which focuses on the largest organ in the body, skeletal muscle, as the key to health and longevity. Her individualized wellness plans include interventions using high-quality protein diets, supplements and resistance training to improve health, reduce chronic disease risk and boost overall energy and wellness by focusing on building and maintaining healthy body composition and lean muscle.

In her private practice, Dr. Lyon leverages evidence-based medicine with emerging cutting-edge science to restore metabolism, balance hormones and optimize body composition with the goal of lifelong vitality. She treats patients of all walks of life – from sarcopenic individuals that want to improve muscle to age independently to overweight and pre-diabetic adults who need to manage weight and improve lean body mass for better health. Her patients also include elite military operators such as Navy SEALS, Green Berets, Army Rangers and Canadian Assaulters, who benefit from her whole-body, whole-person approach, including advanced nutrition interventions, metabolic and genetic testing and personalized behavioral action plans. 

She received her doctorate in osteopathic medicine from the Arizona College of Osteopathic Medicine and is board-certified in family medicine. She earned her undergraduate degree in Human Nutrition from the University of Illinois Urbana-Champaign where she studied vitamin and mineral metabolism, chronic disease prevention and management and the physiological effects of diet composition. She also completed a research/clinical fellowship in Nutritional Science and Geriatrics at Washington University in St. Louis. 

A nationally recognized speaker and media contributor, Dr. Lyon has been a guest on The Doctors and has written for Muscle and Fitness, Women’s Health, Men’s Health, and Harper’s Bazaar. Her subject matter expertise ranges from brain and thyroid health to lean body mass support and longevity.
